HUBBLE SPACE TELESCOPE
DAILY REPORT #1664
PERIOD COVERED: 0000Z (UTC) 06/26/96 - 0000Z (UTC) 06/27/96
Daily Status Report as of 179/0000Z
1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:
1.1 Completed WF/PC-2 6253 (Pure Parallel Archive Program)
The WF/PC-2 was used to execute a pure parallel program taking =
ultraviolet observations running concurrently with prime science =
observations. The intent is to search for extra-galactic sources with =
flux excesses at 3000 A0 and galactic sources with excesses at 1600 A0. =
The observations were completed as planned, and no problems were =
reported.
1.2 Completed GHRS/2/1 6008 (The Atmosphere of IO and Its Interaction =
With the Plasma Torus)
The High Resolution Spectrograph (Sides One and Two) were used to =
make ultraviolet spectrographic observations of the atmosphere of =
Jupiter's moon Io during egress from the planet's shadow. This is to =
study temporal changes in the emission lines of O and S. The observations=
were completed as planned, and no anomalies were noted.
1.3 Completed WF/PC-2 6347 (A Search for Jets in Planetary Nebulae)
The WF/PC-2 was used to make observations of the planetary nebulae =
(class PNe) HE117970 in order to search for the presence of possible =
narrow jets. The current model for PNe formation indicates that jets are =
an unexpected phenomena. Yet there is a growing body of circumstantial =
evidence that suggests narrow jets are common features in PNe. The =
observations were completed as scheduled, and no anomalies were noted.
1.4 Completed GHRS/1 6550 (Understanding the Simplest Symbiotic =
System(s) II.
The High Resolution Spectrograph (Side One) was used to make =
spectrographic observations of an eclipse of the binary system HD117970 =
(aka, RW Hydrae) in order to study their symbiotic relationship. This =
symbiotic star system is one with a red and one hot component and known =
to have emission lines in its spectra. The observations were executed as =
scheduled, and no anomalies were noted.
1.5 Completed WF/PC-2 6193 (PSF Characterization)
The WF/PC-2 was used to make several observational images of the =
large globular cluster Omega Cen using the main photometric filters. =
During these exposures the spacecraft executed a 4X4 dwell scan so that =
the images of the object fell at 16 different locations on the CCDs. =
This is to sample the point spread function (PSF). The observations were =
completed as planned, and no problems were reported.
1.6 Completed WF/PC-2 6509 (Jovian Global Photometry during the =
Galileo Epoch)
The WF/PC-2 was used to make observations of the planet Jupiter to =
coincide which observations taken with the Galileo spacecraft. These =
data will be used to study the vertical aerosol structure of the Jovian =
atmosphere as well as its spatial and temporal variability. The =
observations were completed as planned, and no anomalies were reported.
2.0 FLIGHT OPERATIONS SUMMARY:
2.1 Guide Star Acquisitions:

2.3 Operations Notes:
Realtime operations were conducted uneventfully in the SAMS =
facility from 178/1230Z until 178/2200Z.
A TTR was written for data losses suffered during two scheduled eve=
nts due to severe weather at WSGTU between 179/0321Z and 179/0432Z.
3.0 SIGNIFICANT FORTHCOMING EVENTS:
Nothing at this time.
